Microplastic pollution is a growing environmental issue that involves tiny plastic particles, less than 5mm in size, contaminating marine and freshwater ecosystems. These microplastics can come from a variety of sources, including the breakdown of larger plastic items, microbeads in personal care products, and synthetic fibers from clothing. They pose a threat to aquatic life, as they can be ingested by marine animals, leading to physical harm and potential disruption of the food chain. Research in this area focuses on quantifying the extent of microplastic pollution, understanding its impacts on ecosystems and human health, and identifying strategies to reduce and mitigate its environmental effects.
